A modular system for separating traffic into discrete zones includes a plurality of rail segments pivotally secured to rail mounts. The mounts are configured for rapid and straightforward coupling of rail segments thereto. Moreover, the mounts may be quickly installed and de-installed from a road surface. The overall system therefore provides a physical barrier system that is easily installed and easily modifiable into desired arrangements. Its modular construction of any number of a plurality of distinct rail segments further facilitates customized channelizing design.

A temporary barrier system that is configured to be placed adjacent a concrete divider on a roadway wherein the temporary barrier system provides an increased vertical barrier so as to inhibit seeing therepast. The temporary barrier system includes a storage container having the body of the present invention stored in its first position therein. The body of the present invention is planar in manner and stored in a rolled position in the storage container. The body is wrapped around a winding apparatus and includes an end that is configured to be secured to a deployment vehicle. The deployment vehicle traverses away from the storage container to deploy the body to its second position. The body further includes a plurality of support members being configured to be perpendicular to the upper and lower edge. The storage container is configured as a towable trailer.

The present disclosure relates to an retroreflective structural colour film and a preparation method thereof. The main steps are as follows: (1) assembling colloidal microspheres to form a monolayer of microspheres; and (2) transferring the monolayer of microspheres onto a transparent substrate which has an adhesive layer to make the monolayer of microspheres partially embedded in the adhesive layer to prepare the retroreflective structural colour film. The retroreflective material has the advantages of the simple preparation process, high reflective brightness and uniformity of reflection colour. Moreover, the retroreflective material can exhibit unique retroreflective structural colour under the illumination of a white light source. These characteristics make the retroreflective material especially suitable for nighttime traffic safety applications, for example, to provide a constant colour signal to drivers, and simultaneously to provide dynamically changing colour signal to pedestrians to warn them of approaching vehicles.

A mounting system for driveway marker poles includes a mount body, a coil spring and a ground spike. The mount body includes an upper end with an opening for receiving a driveway marker, the opening leading to an internal axial passage. The mount body includes a lower portion sized to slidingly engage within an upper segment of the coil spring with an interference to retain the mount body to the coil spring. The ground spike includes a threaded upper end with an exterior thread configured to threadedly engage into a lower segment of the coil spring. Systems without a coil spring are also described.

A method of operating an incursion warning system for a work zone, the incursion warning system comprising: a plurality of sensor units arranged about a perimeter of the work zone; and a plurality of alarm units each comprising one or more of an audio, visual or haptic alarm operable to warn a workforce of a potential danger in response to a detected breach into the work area; the method comprising: establishing a geo-zone delimiting a geographical area that includes at least part of the work zone; and a set of rules associated with the geo-zone; deriving an instruction for one of the alarm units determined to be in the geo-zone from the set of rules based on a characteristic of the alarm unit and a characteristic(s) of one or more other alarm units determined to be within the geo-zone; and wherein the instruction is derived in response to a change in a characteristic of the alarm unit and/or the one or more other alarm units and/or one or more of the sensor units within the geo-zone.
